QUESTION:
A sample of an unknown metal has a mass of 35.4 g and a volume of \(3.11\mathrm{\ cm}^3\). Calculate its density and identify the metal by comparison to Table 2.4.
ANSWER:Step 1 of 2
Table 1 Densities of Some Common Substances
\(\begin{array}{lc} \text { Substance } & \text { Density }\left(\mathrm{g} / \mathrm{cm}^{3}\right) \\ \text { charcoal. oak } & 0.57 \\ \text { Ethanol } & 0.789 \\ \text { Ice } & 0.92 \\ \text { water } & 1.0 \\ \text { glass } & 2.6 \\ \text { aluminum } & 2.7 \\ \text { titanium } & 4.50 \\ \text { iron } & 7.86 \\ \text { copper } & 8.96 \\ \text { lead } & 11.4 \\ \text { gold } & 19.3 \\ \text { platinum } & 21.4 \end{array}\)
In this question, it has been given that the mass of unknown metal is 35.4 g and volume is \(3.11\mathrm{\ cm}^3\).
We have to calculate the density of the unknown metal.
